Vesicle

Children are curious little people who find a way of sticking anything and everything in their mouths before their parents can even get a chance to say “NO!” This is one of the main reasons why they are always getting sick and occasionally infecting the people they are in close contact with. The well-known hand-foot-mouth disease is almost always seen in children under the age of ten because of how infectious it is. Unfortunately hand-foot mouth disease is not limited to children. My cousin,…

was to optimize, formulate, evaluate and compare the transdermal gel containing vesicle based: Transfersomes and liposomes, containing Ketoconazole, an anti-fungal bioactive. Ketoconazole loaded Transfersomes were prepared using thin film hydration method with different concentration of surfactant (Span80, Tween80, and Sodium Deoxycholate) and soya lecithin and characterized for various parameters including Vesicles Size, Morphology, Entrapment Efficiency, Drug Loading Capacity, Turbidity…

reactivate and the virus starts transcribing its genes again. It is important to state that once a person has been infected with Herpes Simplex Virus, this virus will remain latent in the hosts body for years and will eventually reactivate periodically causing the disease. Different stimuli can cause the virus to leave its dormant state such as, fever, trauma, emotional stress, sunlight, and menstruation. Herpes Simplex Virus can be transmitted into the host body through direct contact between…

the impulse that is received will spread to the presynaptic axon terminal. There will be a change in the voltage-gated channel of calcium; this will allow the movement of the calcium ions into the terminals of the axon. This will make the synaptic vesicles to bond with the presynaptic membrane, and release their molecules (transmitter) into the synaptic cleft. Some of these molecules will bind to receptor molecules in the postsynaptic membrane. The binding will lead to opening of ion channels in…

notably Syntaxin, SNAP 25 and Synaptobrevin. The seven different serotypes of botulinum toxin have affinities for different SNARE proteins. These SNARE proteins are vital for the synaptic vesicles filled with Acetylcholine to dock to the terminal of the neuromuscular junction when an impulse is received. The vesicles then fuse and release the Acetylcholine into the synaptic cleft. Acetylcholine binds to ligand-gated ion channels, opening them and initiating muscle contraction. By cleaving the…

Nucleus: The nucleus is the control centre of the cell. It’s much like a blueprint that contains all of the instructions on building the body. It contains genetic material called DNA. This DNA has instructions for building proteins and is essential to cell reproduction. If a cell doesn’t have a nucleus for whatever reason will certainly die. The nucleus conforms to the shape of the cell so it could be oval or it could be spherical. The nucleus has three recognizable regions; the nuclear…

terminal. Under specific circumstances, a stimulus will promote the release of dopamine into the synapse. Dopamine transporters will then remove the dopamine from the synapse so that vesicular monoamine transporters can store the neurotransmitter into vesicles, release it, and protect it from oxidation (Riddle et al, 2006). Damages in dopamine transporters or the vesicular monoamine transporters will cause…

large biological molecules by vesicles which fuse to the plasma membrane. This is mainly done by secretory cells and gets rid of substances like insulin or neurotransmitters. Endocytosis, however, allows the cell to take in substances. Vesicles pinch off from the plasma membrane, allowing the bulk into the cell. Endocytosis comes in three forms: phagocytosis, when a cell engulfs a substance entirely, pinocytosis, when the cell takes the substance in by small vesicles (like small gulps), and…

My article is about diabetic insulin patches and how they affect people with diabetes. Diabetes is a disease caused by the pancreas not producing insulin which aids the body in sugar digestion. Currently insulin pumps are being used. “Insulin pumps are cell-phone-size devices that deliver preprogrammed and user-adjusted doses of insulin (Chait).”The pumps have to be manually set to inject the insulin using carbohydrate counting; however, they also alert the diabetic to low sugar and high sugar…

Cell Biology Beta cells in pancreatic tissues are described as eukaryotic cells and not prokaryotic, this is because the cell is larger in size and there is a true nucleus present which contains DNA. In prokaryotic cell there isn’t a nucleus and the DNA is free within the cytoplasm. Also Beta cells have many organelles and there is mitochondria present, which in a prokaryotic cell there are fewer organelles and there aren’t any mitochondria present. Beta cells in the pancreatic tissue release…
